Solving An Inverse Control Problem Using Predictive Methods, Chad J. Davis
Solving An Inverse Control Problem Using Predictive Methods, Chad J. Davis
Theses and Dissertations
Model Predictive Control is the class of control methods that optimizes a specified performance index in order to minimize the weighted future output deviations from a setpoint trajectory. This thesis applies MPC in the inverse sense -- known aircraft outputs are applied in the performance index as setpoints in an attempt to determine what control histories caused those outputs. Using this method, aircraft mishap investigators could then have a means of determining what the control surface deflections were throughout an incident since Flight Data Recorder data does not include control surface deflections. The actual Flight Data Recorder data from aircraft …
Robust Eigenstructure Assignment Using Positive Definite Output Feedback Control, Adam G. Harris
Robust Eigenstructure Assignment Using Positive Definite Output Feedback Control, Adam G. Harris
Theses and Dissertations
This research investigates a method of eigenstructure assignment for the classes of controllers known as positive definite output feedback control. The research began with a closed loop system with output feedback control that utilizes a collocated actuator-sensor pair. It is shown that this system is robust because it is globally stable for positive definite feedback. Analytical analysis is then completed to determine gains that minimize a cost function that is the error between the desired and achievable (assuming positive definite output feedback) eigenstructure. Examples are given at the end of the thesis to validate the computer code and theory results.
